They can cohabitate well, reducing competition for resources and maintaining a balanced ecosystem. They do not have predatory tendencies but they can become targets for larger, aggressive species.
Diet & Feeding
Bamboo Shrimp are omnivorous, filter-feeding creatures that have a unique method of obtaining nutrients. In the wild, their natural diet consists of tiny particles such as plankton and algae in the water. For captive bamboo shrimp, however, a high-quality, balanced diet suitable for filter feeders should be adopted for their health and well-being.
Primary Food Sources in the Wild
In the wild, Bamboo Shrimp are mainly filter feeders that primarily feast on tiny particles. The food they consume typically comprises microscopic organisms such as algae, plankton, detritus, and other organic material suspended in the water column.
Settling near high-flow areas, these shrimps use their fan-like appendages to catch and feed on these minuscule food sources, which are both nutritious and necessary for their survival.
Recommended Diet in Captivity
In captivity, Bamboo Shrimp’s ideal diet includes a variety of fine, powdered foods designed for filter feeders such as powdered algae or baby shrimp food. They can also feed off the biofilm in the aquarium.
Since Bamboo Shrimps are scavengers, they will sometimes eat leftover fish food or dead plant material. It’s crucial to ensure they have constant access to food in the water column to mimic their natural feeding behavior in the wild.
Frequency of Feeding
For optimal health and longevity, Bamboo shrimp should be fed once or twice daily. These invertebrates are filter feeders: they fan their large front legs in the water, capturing microorganisms and detritus to feast on.
In captivity, if the tank is insufficiently stocked with food particles, supplement with high-quality shrimp food. Timing and portion control are key, as overfeeding can harm their health and pollute the tank.
Unique Feeding Behaviors
Bamboo Shrimp have a fascinating feeding behavior, which sets them apart from other aquatic species. They are filter feeders, using their specialized fans located on their front appendages to capture tiny food particles from the water column.

This unique feeding behavior makes them an interesting addition to any aquarium, but it also requires owners to ensure an adequate supply of suspended particles for them to feed on.
Breeding & Reproduction
Breeding and reproduction in the Bamboo Shrimp refer to the methods and conditions required for their successful mating, egg-laying, and rearing of offspring. These aspects involve intricate mating rituals, specific egg-laying processes, favorable fertility and hatching conditions, and certain measures taken for the care of their young.
Mating Rituals
In the world of Bamboo Shrimp, mating rituals are simple yet distinct. The male shrimp typically initiates mating by depositing a spermatophore (a packet of sperm) near the female. Subsequently, the female passes her eggs over the sperm to fertilize. Mating frequently happens after molting, when the exoskeleton of the female is soft, which makes the process easier.
For successful breeding in captivity, it’s vital to provide a stress-free environment that closely mimics the shrimp’s natural habitat.
Egg-Laying Process
The egg-laying process of bamboo shrimp constitutes the female releasing eggs into the water after fertilization, which she carries under her swimmerets. She then agitates the water to disperse the eggs.
The unfathomable number of eggs, often into the thousands, increases the chances of survival despite the lack of parental care post-hatching. During this process, it is crucial that the water conditions mimic their typical natural habitat with a high level of aeration and optimal temperature.
Fertility and Hatching Conditions
In terms of fertility, Bamboo Shrimp females produce several hundred eggs at a time, which they carry in small clusters under their stomach. The hatching process involves a larval stage, requiring the availability of brackish water.
The exact water parameters for successful hatchings include a temperature of 27-28°C, moderate to high hardness, and a salinity of around 15-20 ppt. These conditions emulate the mix of fresh and saltwater the eggs would encounter in their natural habitat, typically near river mouths.
Care for Offspring
In the wild, Bamboo Shrimp offspring are virtually left to fend for themselves after the eggs are released. The eggs hatch and float as larvae in the water, where they eventually evolve into juvenile shrimp. While in your aquarium, ensuring that the water quality remains high can enhance the chances of survival for the offspring. Providing ample hiding places using plants or rocks will also aid in their survival.
Aquarium Care
Taking care of Bamboo Shrimp in an aquarium environment requires you to simulate their natural habitat as closely as possible. This involves catering for their specific size, substrate and decoration preferences, and ensuring optimal water conditions.
